PAI'EE-CLIP.

Specification of Letters I's/cent.

Application filed April 25, 1919. Serial No. 292,706.

1 'a att 'w kom it may boncem:

Be it known that I, CLARENCE C. COLLETTE, a citizen of the United States, and aresident of .Amsterdam, in the county of Montgomery and State of New York, have invented a certain new and useful Paper-Clip; and I do hereby declare the following to he a full, clear, and exact description of the'in' vention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to 'the aecompanying druwin and to the characters of reference marke part of this specification.

My invention has for its object to produce a means for securing a plurality of sheets together, commonly known as a paper clip wherein are formed sharply pointed pror jections for penetrating and engaging the sheet material, such as paper, to prevent re-` moval of the clip or the scparation oi" one or more of the sheets from the clip. In my in- Vention the projecting points are .located. on the opposite sides of a bent clip having its parts preferably located in the same plane, it being particularly adaptahle to a clip which is of the form of a fluttencd ohlong spiral well known in the Stationary arts.

An embodiment of the invention is illustrated inthe accompanying drawings, it he ing understood, however, that the clip shown may be modified in form and yet contain my invention.

Figure 1 of the drawings, illustrates a top View of the clip containing the invention. Fig. 2 illustrates an edge view. Fig. 3 illustratcs an enlarged View of a part of the clip 'and Fig. 4 illustrates a View of the clip 'when applied toshoets of paper or fabric.

Fig. 1 is a cli having the two parallel legs 2 and 3 Which terminate in the returned portions 4 and 5 also disposcd in parallel relation and ext/ending along and in proximity to the portions 3 and 2, respectively. The parts of the clip are located in sulJst-aw tially the same plane and the portions 5 and 3 are located within the portions 2 and 4 and the curved portion 6 connecting the portions 3 and 5 is located within the clip and near the curved portion 7 that connects the portions 2 and 4. The clip is provided with projecting sharply pointed teeth 8 located thereon, which form a located in substantially paralleled lines ex'- tending across the clip and'on opposite sides of the clip. The pointecl teeth on the one side of the cli `are preferably located at points intermeciate the projecting teeth of the other side so that when papers are slipped between the curved portions 7 and 6, they will be engaged by the teeth on opposite sides of the clip and the teeth of one side will penetrate the papers intermediate the points that the teeth on the opposite side of t e clip penetrate the Japer. This will occur irrespective as to w ether the cnrved portion 6 is placed on one side or the other side of the papers, that is, whether the curved portion 6 is placed on the front or the hack of the apers. When the clip is positioned over tie papers to the point of securement of the papers, the shar ly pointed teeth will penetrate and engaget e papers and thus securely bind them together. This is )articularly true not only because of the shurpness ofthe ointed teeth, but also because the points o their engagement on opposite sides of the papers alternate and the teeth penetrate the paper at alternate points on opposite sides of the paper. The pointed teeth are formed by cutting with a sharp instrument into the oylindrical surface of the wire of the clip which produces a gradual rise of the material of 'the wire on opposite sides of the cutting instrument and a very sharp surface that extends toward the axis of the cylindrical surface within the cut so that when the clip is slipped over the papers, 'the papers will quite readily )ass over the points, but when the clip'is allowed to remain on the papers and particularly when the papers are handled a little, the sharp points penetrato the papers more completely than during the sliding movement of the papers when they are inserted into the clip and consequently the papers are securely held by the clip.

I claim :-r-

Patented May 17,1921;

A clip for sheet material comprising a. I

.U. !yin ithout en d hes ide the first named leg'of he !J -sharp pointed rojections Ioc'ated mi opposite sides of t e legs of the U an the returned portions thereof the projections of opposite sides of.the clip bemg alternately located along the c'li and so that thespmjections *on one side w' be located at points along the elip intermediate the projections on the opposite side when the legs of the U and theureturned portions clamp opposite sides of the sheet material.

In testimony whereof I have hereunto signed my name to this specification. 4 CLARENCE C. COLLETTE.
